Abstract

The present invention includes a body having a storage compartment defined therein, a door for opening and closing the storage compartment, a lifting member, which includes a handle and a first gear extending in a vertical direction and which is disposed at the door in a manner of being movable upward and downward, a second gear, which is disposed at the door so as to engage with the first gear, a third gear, which is disposed at the door so as to engage with the second gear, and a pushing member, which is disposed at the door so as to be movable in forward and rearward directions and which includes a fourth gear engaging with the third gear, the pushing member exerting external force on the body when the lifting member is lowered, thereby offering an advantage in that a user such as a child, who is short, can easily open the door.

First claim

The invention claimed is:

1. A refrigerator comprising:
a body having a storage compartment defined therein;
a door for opening and closing the storage compartment;
a lifting member, which includes a handle and a first gear extending in a vertical direction and which is disposed at the door in a manner of being movable upward and downward;
a second gear, which is disposed at the door so as to engage with the first gear;
a third gear, which is disposed at the door so as to engage with the second gear; and
a pushing member, which is disposed at the door so as to be movable in forward and rearward directions and which includes a fourth gear engaging with the third gear, the pushing member exerting external force on the body when the lifting member is lowered,
wherein the lifting member further includes a fifth gear, which extends in forward and rearward directions and engages with the third gear when the lifting member is in an upper position.

2. The refrigerator according to claim 1 , wherein the fourth gear is disposed on the third gear.

3. The refrigerator according to claim 1 , wherein the door includes a lifting member guide, which serves to guide upward and downward movement of the lifting member and to restrict forward and rearward movement of the lifting member.

4. The refrigerator according to claim 1 , wherein the door has a blind hole through which the pushing member passes.

5. The refrigerator according to claim 1 , wherein the door includes a pushing member guide for guiding forward and rearward movement of the pushing member.

6. The refrigerator according to claim 1 , wherein the pushing member includes a rear end, which serves as a contact end that either contacts the body or is separated from the body.

7. The refrigerator according to claim 1 , wherein the third gear is configured to be larger than the second gear.

8. The refrigerator according to claim 1 , wherein the fifth gear is disposed so as to be perpendicular to the first gear and such that a portion thereof is positioned under the third gear.

9. The refrigerator according to claim 8 , wherein the third gear is disposed between the fourth gear and the fifth gear.

10. The refrigerator according to claim 8 , wherein the fifth gear is positioned to be parallel to the fourth gear.

11. The refrigerator according to claim 8 , wherein the fifth gear is separated from the third gear when the lifting member is lowered.

12. The refrigerator according to claim 1 , further comprising an elastic unit, which is installed at the body so as to elastically bias the door in a direction in which the door is opened.

13. A refrigerator comprising:
a body having a storage compartment defined therein;
a door for opening and closing the storage compartment; and
a door pushing unit, which pushes the door outward by reaction force that opposes an external force that is applied to the door, when a handle is lowered,
wherein the door pushing unit comprises an interlocking unit and a pushing member, the interlocking unit having:
a lifting member including a handle; and
an external force transmitting unit for moving the pushing member forward or rearward upon vertical movement of the lifting member, the external force transmitting unit including:
a first gear provided at the lifting member so as to extend in a vertical direction,
a second gear provided at the door so as to engage with the first gear;
a third gear provided at the door so as to engage with the second gear; and
a fourth gear is formed at the pushing member so as to extend in a forward and rearward direction,

wherein the door includes a lifting member guide for guiding upward and downward movement of the lifting member and restricting forward and rearward movement of the lifting member, and
wherein the lifting member further includes a fifth gear, which extends in forward and rearward directions and engages with the third gear when the lifting member is in an upper position.

14. The refrigerator according to claim 13 , wherein the fifth gear is disposed so as to be perpendicular to the first gear and such that a portion thereof is positioned under the third gear.
